I successfully compiled libjpeg-turbo libraries in my android app following the recipe here: libjpeg-turbo for android.
Trying to assess the performance improvement of NEON SIMD instructions in the library, I tried to enable/disable NEON support. Interestingly, no differences.
Digging through the code, looks like init_simd() in jsimd_arm.c is never executed at runtime.
This function is called by libjpeg_arch_specific_init() which is called when the library is first loaded.
I believe the glitch originates from this library being static as opposed to dynamic, hence never "loaded" (see comment from DRC at end of this thread: http://sourceforge.net/p/libjpeg-turbo/patches/26/)
Does it make sense? Anyone else seen this issue?
Thanks!
